OILER.

' sPEc'IFIcATIoN forming part of Letters Patent No. 402,632, dated May 7, 1889.

Application filed October 4, 1888.

. To @ZZ whom it may concern:

Be it known that we, WEBESTER FOREMAN `TRAVES and CHAELEsEDwAED TRAVES, citi-A .zens of the United Statesresiding at Los Angeles, in the county of Los Angeles' and State of California, have invented a new and useful Momentum-Actuated Repeating Oiler,

. of which the following is a specification. Our invention relates more particularly to Oilers for crank-pins and other bearings havv inga gyratory motion.

The object of our invention is to devise an 011er which will collect the oil after it has once been used in oiling a bearing and will return it to the top of the bearing to be used again, thus'using the oil repeatedly with but little waste. We accomplish this by means v e of the device described herein and illustrated tx in the accompanying drawings, in which- 2O Figure l is a longitudinal vertical section 4of the end of a-crank-rod on a steam-engine provided with our improvement. Fig. 2 is a` detail of the regulating-valve in the feed- .cup with the valve open. Fig. 3 is a view of the regulating feed-valve closed. Fig. 4 is a perspective view of thecollecting-cup, one.. side being broken away. Fig. 5 is a plan view of the collecting-cup. Fig. i6 is an enlarged vi'ew of the valve. Fig. 7 is a .cross-section of the same on line oc m. Fig.

8 is a sectional view, showing the opening in the bottom of thebearing in which the crank- .pin is seated. Fig. 9 is a cross-section of the .lower strap, D, on line y, Fig. 8.

.upon the inertia of the oil and the valve and The operation of ourinvention depends the gyration of the oiler, and the principle of the invention is that if a suitable conduit be properly arranged leading from the collectingcup at the bottom of the bearing to the feeding-cup at the top of the bearing the inertia of the oil, when properly controlled by a suit- `able valve, will cause the oil to flow through such conduit from the collecting-cup up into the feed-cup.

Our invention comprises the combination, with a gyratory bearing, such as a crank-pin, crank-rod, and brasses, of a feed oil-cup lou cated above the bearing, a collecting oil-cup Serial No. 287,252. (No model.)

located below the bearing, a feed oil-passage between the feed oil-cup and the bearing, an escape oil-passage between the bearing and the collecting-cup, a cross-partition in the collecting-cup between the escape oil-passage and one end of the collecting-cup, a passage through such partition, a momentum-actuated valve for such passage to allow the oil to flow into the discharge-chamber from the receiving-chamber and prevent its return, and a tube connecting the exterior end of the collecting-cup with the top of the feed' oilcup.

Our invention also comprises other features and details hereinafter more fully set forth.

The oiler shown in the drawings is the most approved form, andis adapted for use on both stationary and locomotive engines; but differand the -valve in the feed-cup may be dispensed with without destroying the utility of our invention. We therefore do not wish to the momentum-valve L M N.

The feed-cup A is seated in the top strap, B, in the ordinary manner, and the collectingcup C is secured to the bottom strap, D, under the crank-pin E. There is a feed oil-passage, F, between the Vfeed-cup and the crank-pin, and an escape oil-passage, GG W, between the crank-pin and the collecting-cup. The collecting-cup is provided with a cross-partition, H, dividing it into two chambers. The escape oil-passage G opens into one of these chambers,'P, which we call the receivingchamber, and the returning-tube I opens from the exterior end of the other chamber, Q, .which we call the discharge-chamber, and extends to and opens into the top of the feed oil-cu p.

The partition l'l is provided with a passage, J, therethrough,which is provided with a suitable valve adapted to be opened and closed by the momentum imparted by the .gyration of the oiler when the crank is rotated.

The feed oil-cup may be provided with the feed-regulator Kor other suitable regulator,

if desired; but a regulator is notv absolutely ent valves maybe used in place of those shown,

be limited bythe feed-valve nor the form of ,i

essential to the operation of our invention. The valve employed by us to close the passage through the partition consists of a metal pin, L, approximately equal in diameter to the diameter of the passage, seatedin the passage, and providedzat one end with a head,M, and having longitudinal grooves N in the body of the pin from the head to the end of the pin to` allow the passage of the oil along the pin. A stop, U, located in the path of the pin, prevents it from being thrown out of the passage J.

XVe provide a filter, O, in the receivingchamber beneath the escape oil-passage G, so that the oil which falls into the receivingchamber P will be filtered before it reaches the discharge-ch amber. The lter preferably slants from the top of the partition to the floor of the chamber, near the exterior end thereof, and an opening, R, closed by a plug, S, .or other suitable means, is provided in the end of the chamber to allow access into the chamber, so that the sediment from the oil may be removed. The collecting-cup is preferably secured to the strap by screws T, so that it can be removed at pleasure.

The partition II is not flush with the top of the walls of the collecting-cup, space being left'between the top of the wall and the face of the strap for the upper end of the filter, which is seated beneath the oil-passage, to be clamped between the partition and the strap without opening the joint between the collecting-cup and the strap.

In the drawings the filter is not illustrated in detail, as there is nothing novel in the formation of the screen through which the oil passes. It should be of close enough mesh to intercept the impurities which may mingle with the oil in passing around the pin.

The oil-regulator K is an apex split cone of spring metal, the tendency of the elasticity of which i's to spread the points of the divided apex apart. The outer face of the cone is threaded, and a nut, X, is screwed down upon the upper .end of the cone to draw the points toward each other, thus closing the split. The regulator is seated in the oil-passage at the bottom of the feed-cup, and is provided with an axial passage, Y, forming an outlet through the base of the cone from the split in the apex thereof.

The, means for collecting the oil and conducting it from the bearing to the collectingcup comprises a space, as G left between the brasses V V, extending from side to side beneath the bearing to allow the oil to pass from the pin to the bottom strap, a groove or gutter, WV, extending almost from side to side of the top of the strap beneath the space G', and sloping downward from each end toward the middle of the gutter, and the central passage, G, opening approximately at the middle of the gutter and extending downward through the bottom strap to the collecting-cup. NVhen the oiler moves in one direction, the oil and the valve L M N are displaced by their inertia and enter the discharge-chamber. When the oiler moves in the opposite direction, the valve, being heavier than the oil, will seat itself in the passage before the oil can enter the passage and return to the receiving-chamber. 'lhus at each movement in one direction oil is forced into the discharge-chamber and will be forced up the return-tube I, and passes into the feed-cup.

Now, having described our invention, what we claim as new, and desire to secure by Letters Patent, is-
